bug#1782: 23.0.60; Cursor movement not fluent

[Jules Colding]

CVS Emacs has in the last few days developed a problem with cursor movement. The cursor 
moves in "jumps", not fluently as it should. This holds true for vertical as well as 
horizontal movement. It is like a small waiting period has been inserted between each 
movement of the cursor for every 2 or 3 characters. The problem is more visible in 
terminal mode.

I don't experience this.  Could you try rolling back to prior revisions
and try to find out when this problem first appeared?

Sure. Now, cvs is not my strong side. How would I roll back, say, a  
week with cvs?

OK, false alarm. I haven't rebooted my laptop in weeks. Something must  
have gone bad although top didn't show any high activity.

A reboot was the cure. Sorry for the noise.

Best,

Does this happen with "emacs -Q"?

If not, perhaps your site file and .emacs loads something that puts
some function on post-command-hook.

To roll back to, say, the 20th of December:

cvs up -D 2008-12-20

To return to the latest version of CVS:

cvs up -A
